ASTM B306 Copper Tubes for Drain, Waste and Vent - Dimensions and Working Pressures
Dimensions of copper tubes ASTM B306 Drain Waste and Vent - DWV.
Copper tubes according ASTM 306 are used in soil, waste, vent, solar and storm drainage piping systems.
DWV stands for "Drain, Waste and Vent" and is pipes recommended for above ground use only, no pressure applications and sweat fittings only..
